Game stuttering and can't figure out why

[NOTORIOUS N8]

I thought I figured it out and it was the terraforming I did on my map. But I've seen so many people do as much or more than me and having 0 issues. I've seen people with massive bases and no issues. But for some reason when I try moving around my game it stutters and acts like the frames are dropping.

It's not an issue of not having the power. I have an i9/3090 so my computer has plenty of power to run the game and I see people with less running better. I've tried all the little tricks to improve FPS to try and fix it, but it's not changing. Even tried different seeds.

Anyone have any issues like this and find a fix? It's killing me as I really really like this game and want to play. But I'm out of ideas on how to fix it.

>>>>>>> UPDATE 2/22/21 <<<<<<<<

The Devs are now aware of this issue as a mod from their Discord managed to pass along all the info I had about it. So although waiting sucks, we just have to give them time to get around to fixing it.

Running on a 2060 laptop here with AMD Ryzen 7 2.30Ghz and I have the same problem
Stutters happen when i walk around, Doing things that have smoke effects, and it still happens even after i put every graphic options on low and disable everything.

I tried opening my task manager, my CPU and RAM are running under 50% when the stutter happens so the problem shouldn't come from there...

Would love to see any fix

Me too, it's killing me not being able to dive into this game. I was even going to make some fun YouTube content for it. But this just sucks.

I even tried changing all the PC settings, disabling overlays, shutting down every other software, turning my settings way down, changing the lodbias to 1. Nothing works, so it's got to be a game bug that affects some and not others or maybe a memory leak. Just hope it's fixed soon.

But I'm 100% certain that those of us with the issue is not coming from our PC or anything. It's for sure a game related issue.

You didn`t say what you`ve actually tried yet, but for me switching to "fast vsync" through the Nvidia Control Panel is what fixed it.
Before doing that, the game was stuttering all the time for me, no matter the settings.
Now it`s mostly smooth 60 at 4k, just a few small drops and sometimes short freezes from loading.

Fast VSYNC fixed the stuttering for me as well. Thanks for the tip

I didn't see anything about "fast vsync" anywhere, but I can give that a try. From what I've read all over vsync is causing issues with the game not fixes. But I'll see what it does.

I'll have to look at everything I've changed as I can't list it off the top of my head. But I'll see if I can figure that out later if needed to fully list it. I did turn off vsync and tried even turning on Gsync, then back off when it didn't help. I turned off overlays and any extras that might affect it. I tried turning on the true full screen mode. In the game I turned off any extra settings, I turned of and on vsync, I turned off camera shake. I even tried turning off all the graphic improvements as whole and still seen no changes other than my fps going up.

I'm part of another forum that someone was working with a dev (not of this game) and they think it's due to a memory issue. Still looking into that more.

From what you're saying though it doesn't seem like you fixed the issue by turning that on. From who I've talked to, videos I've watched, and playing on my girlfriends pc who doesn't have the issue... you should see zero stuttering and freezes.

I can confirm that Fast Sync does absolutely nothing to fix this issue. If you are seeing improvements then you don't have the bug myself and others are running into, you just have a pc with screen tearing.

I actually had the same issue with my 2080super, and 10700k. Massive stutters, was unplayable. I also tried the fast Vsync option, but it didn't help. What did help was the Boot file.

Go to C:\Program Files (x86)\Steam\steamapps\common\Valheim\valheim_Data, then open the "boot" file as notepad and add:

gfx-enable-gfx-jobs=1
gfx-enable-native-gfx-jobs=1

to the very top. This was the single biggest thing to help the stutters for me. It still does stutter, but nowhere near as often, and is totally playable now. Give that a shot!

add this line to the game's launch settings in steam; -window-mode exclusive

The game is using some kind of forced windowed-fullscreen (for some reason), so your PC is not utilizing it's full potential for the game. That fixed some of my fps issues I had previously.

You've just fixed a stuttering problem I've had system wide for years..

Thanks so much. If I could suck your ♥♥♥♥ I would.


















No ♥♥♥♥

Tried that before with no help sadly.

This is something I haven't tried or seen. Before I do this what exactly is that doing to the game? Just want to verify before I screw something up.

Are you sure about this? Simply mentioning what CPU and GPU you have doesn't cover the whole computer, or whether or not it is optimized/tuned well. The drive in particular has everything to do with reading/writing, and considering all the terrain changes you claim to have made, a slow drive would just compound that more until it was actually a problem.

I haven't made any tweaks to the game whatsoever, nor to the launch command, and I get 60 FPS everywhere (capped). But then, I have a highly optimized rig that also has a 20GB Level 1 memory cache against a fast NVMe drive, so reading/writing data is almost instant for me. That, and the rest of the rig is very highly tuned for gaming.

Perhaps you'd like to post some more specs, along with what you've done to tune your gaming machine.

I'm not sure how it works honestly. Just posting what helped me a lot here. I'm 60 hours deep with these two lines in, and it's stable.

Thanks, I did look online and found some more people talking about this. Tested it on my original map with lots of terraforming and on my fresh map like I did with all the other things. The original map was a no go, major terraforming is just a mess right now and being anywhere near it is horrible. But on the fresh map with little terraforming for a building it does seem to be a good amount better. Not fixed... but at least better from what I can tell. So I'll just have to start fresh and deal with it.

I still really hope the devs are working on this and trying to fix it. Really sucks to have to go to this much work to play a game when anything else I have runs amazing.

Go talk about how good you tuned your PC somewhere else. You can play this game on a mechanical drive in a laptop with a 1660 and run good at 60 fps, which I know someone who's doing that. This is some kind of memory leak issue or some bug affecting a handful of people so you aren't helping talking about how great you tuned your machine.
